L, a conventional dual-lamp illumination system 100 includes a first lamp 110, a second lamp 120, reflector 130. 其中,第一灯具IIO与第二灯具120相对,而反射器130被配置于第一灯具IIO与第二灯具120之间。 Wherein the first lamp and the second lamp 120 IIO hand, the reflector 130 is disposed between the first lamp 120 and second lamp IIO. 反射器130具有两个反射面132、134,且其与轴线50之间的夹角分别为45度。 Reflector 130 having two reflective surfaces 132, 134, and the angle between the axes 50 and 45 degrees respectively.

如上所述,第一与第二灯具IIO、 120分别包括灯芯112、 122和抛物面灯罩114、 124。 As described above, the first and second lamp IIO, 120 each include a wick 112, 122, and parabolic shade 114, 124. 灯芯112、 122适于提供发散光,它们位于同一轴线50上,而抛物面灯罩114、 124用以使发散光形成平行光束112a、 122a,且此两平行光束112a、 122a的光轴平行于轴线50。 Wick 112, 122 adapted to provide a diverging, they are located on the same axis 50, and the parabolic lamp cover 114, 124 is formed for causing diverging parallel beam 112a, 122a, and the optical axis of these two parallel beams 112a, 122a is parallel to the axis 50 . 此外,部分平行光束112a、122a经由反射器130的反射面132、 134反射而形成合成光束140。 Further, the parallel beam portions 112a, 122a 132 via the reflecting surface 134 of reflector 130 and combined beam 140 is formed. 未被反射器130反射的另一部分平行光束112a、 122a经由抛物面灯罩124、 114反射至反射器130,再由反射面134、 132反射而形成合成光束140。 Another part 112a parallel beam 130 reflected by the reflector not, 122a via the parabolic shade 124, the reflector 114 to the reflector 130, and then by 134, reflecting surface 132 is formed combined beam 140.

在所述双灯照明系统100中,由于平行光束112a、 122a分别直接照射第二与第一灯具120、 110,且反复经过灯芯112、 122,所以容易造成灯芯112、 122过热而损坏。 In the dual lamp 100 in the lighting system, since the parallel light beams 112a, 122a are directly irradiated to the first lamp 120 second, 110, and 112 are repeated to wick, 122, it is easy to cause wick 112, 122 overheating and damage. 此外,由抛物面灯罩114、 124所形成的平行光束112a、 122a会逐渐发散,且因平行光束112a、 122a的光程较长,使得光束收集效率较差,也因此降低了双灯照明系统IOO所提供的照明光束的强度。 In addition, parallel light beam by a parabolic 112a lampshade 114, 124 is formed, gradually diverging 122a and 112a due to a parallel light beam, a longer optical path 122a so that the light collection efficiency is poor, thus reducing the dual lamp illumination system IOO the intensity of the illumination beam provided. 另外,这种双灯照明系统IOO利用第一灯具IIO与第二灯具120相对设置,并于第一灯具110与第二灯具120之间设置反射器130来合成光束,故需较大的空间来配置这种架构,致使投影装置的体积较为庞大,在现今电子产品追求短、小、轻、薄的趋势下,此种架构的双灯照明系统100显然不能满足现今的设计需求。 Further, by using such a dual-lamp illumination system IOO IIO first lamp and the second lamp 120 disposed opposite and in the first lamp 110 and second lamp 120 disposed between the reflector 130 combined beam, it takes a larger space this architecture configuration, resulting in relatively large volume projection device, in today's electronic products, the pursuit of short, small, light, thin trend, this architecture dual-lamp lighting system 100 obviously can not meet the needs of today's design.
